Hi!
It's not about 'right' (why would grepping Guix return wrong code...?
Impossible! :-). It's a matter partly of preference and partly of using the
best tool for the job.
Omitted from your second example is a call to list, and the #~ that both have
in common is just syntactic sugar for (gexp ...).
So the two forms you're comparing are:
(gexp '("a" "b" "c"))
(gexp (list "a" "b" "c"))
Both are completely equivalent when they contain only strings. Choose
whichever you like.
When you have several procedures to call, calling 'list' can look cleaner:
(list (string-append "foo=" bar) "baz")
Although strictly speaking ` uses fewer characters and is just as correct:
`(,(string-append "foo=" bar) "baz")
Most Guix developers prefer (list ...) because it's more self-explanatory to
people unfamiliar with Lisps. However, 'quoting is such a fundamental building
block that it probably matters little in practice.
Your name looks familiar so I'll assume you understand basic Lisps concepts
like quote & quasiquote. If not, I strongly suggest learning the basics, it
will make Guix much less mysterious.
As long as configure-flag gets a list, it matters little how you construct it:
#~(append (list "my" "flags")
'("are" "many")
(string-append "colo" "ured"))
Just be consistent.
Kind regards,
